Sleeping too much increases the risk of dementia? Maintaining a stable sleep time is key
Recently, a study published by Miami Miller University in Florida states that people who sleep 9 hours a night have markedly reduced memory and language skills, which are early symptoms of dementia such as Alzheimer’s disease.The study investigated 7 years of sleep in 5,247 Hispanic Americans aged 45 to 75 years.It was found that for people who sleep for 9 hours each night, their cognitive ability has dropped, learning ability has dropped by 22%, language fluency has dropped by 20%, and memory has fallen by 13%.As soon as the news came out, there was a lot of public discussion, and many people were even more worried. Does long sleep really have anything to do with dementia?In response, Yin Guoping, a young member of the Chinese Sleep Research Society and chief physician of the Department of Otorhinolaryngology Head and Neck Surgery at Tsinghua University Beijing Tsinghua Chang 合肥夜网 Geng Hospital, said in an interview with the reporter of Science and Technology Daily that there is a large amount of evidence indicating insufficient sleep (usually less than 6 hours per day)Decreased deep sleep due to certain sleep disorders (such as sleep snoring) can increase beta amyloid concentrations in the brain, which can damage cognitive functions in the brain and increase the risk of dementia.Good sleep can help the brain clear the beta amyloid in the brain and reduce the risk of developing dementia.Interestingly, studies have pointed out that too long sleep periods (usually referring to more than 9 hours per day) may also increase the risk of dementia.A large sample of follow-up studies showed that people who sleep more than 9 hours a day are about twice as likely to develop dementia as those who sleep less than 9 hours.Follow-up results from several different populations also reached similar conclusions.”However, it is important to point out that the results of these studies only prove the correlation between excessively long sleep and dementia, not the exact causal relationship.Yin Guoping said that some scholars believe that excessive sleep may be an early symptom of dementia.”It should be noted that the length of sleep varies from person to person, and a small number of healthy people will show that the reasonably long or short sleep time is born.Therefore, if a person’s sleep time has remained relatively stable and does not affect his normal physiological function and ability to work and live, it can be considered normal.But if there is any obvious change in sleep time or state, it should be paid attention to and seek medical treatment as soon as possible to avoid serious complications.Yin Guoping emphasized.(Reporter Fu Lili)
